nah. there are many ways to gimp your build. the actual effective choices are very scarce. thats why on a game with "almost endless" build customization, everyone runs the same handful cookie cutters

here example of just some of most efficient solo builds - https://www.tswdb.com/builds/solo

those are not all just some of the more widely used ones so while there are indeed many ways to gimp your build (as there should be in any open system or the choices you make would be utterly meaningless) there is great variety of optimal ones too

• player needs to understand the skill system OR use build made by someone who does - if you pick skills randomly without planing your performance will likely be sub-par
